"Firefox OS could actually be wildly successful, no matter how underwhelming the actual phones may be. And that's because - at least for now - you're not the customer; your carrier is." I'm extremely disappointed by Firefox OS so far. There's nothing wrong with the low-end hardware we've seen during MWC, but there is something wrong with low-end hardware that can't even properly run its operating system. To make matters worse, carriers are the boss here. Terrible first impression.
